[0032] Referring to Figure 1 and Figure 2 The utility model provides a kind of fire-fighting hand lamp 10, it includes: lamp body 100, lamp cap 200, handle 300, power supply 400, LED lamp plate 500 and laser search assembly 600;Power supply 400 provides electric energy for LED lamp plate 500 and laser search assembly 600, LED lamp plate 500 is used to provide illumination, laser search assembly 600 can emit laser, help firefighter to identify fire source position in thick smoke, the distribution position of low visibility environment, the position of team mate, avoid misjudgment or miss information, improve the safety of rescue action.
[0033] Referring to Figure 2 and Figure 3 Handle 300 includes grip 310 and transition part 320, transition part 320 is connected with lamp body 100, and installation hole 321 is formed in transition part 320, and installation hole 321 is used to accommodate laser search assembly 600;
[0034] Referring to Figure 3 and Figure 4 Laser search assembly 600 includes silica gel sleeve 610, laser emitter 620, lens 630, lens 640 and compression ring 650, laser emitter 620 is located in installation hole 321, silica gel sleeve 610 wraps laser emitter 620, silica gel sleeve 610 is abutted with the hole wall of installation hole 321, lens 630 is attached with the emission end of laser emitter 620, lens 640 is embedded in compression ring 650, compression ring 650 is arranged at the hole mouth of installation hole 321, and compression ring 650 and installation hole 321 are detachably connected;
[0035] The light beam generated by laser emitter 620 is emitted towards target direction after passing through lens 640.
[0036] Wherein, compression ring 650 can be replaced with different lens 640, so that the light beam emitted by laser emitter 620 presents different shapes to meet actual use requirements.For example, the light beam presents "one" shape after refraction by lens 640;Or the light beam presents "ten" shape after refraction by lens 640.Further, rotating compression ring 650 can make lens 640 rotate, so that the angle of emitted light beam changes, making the use of laser beam more flexible.
[0037] During the rescue mission, firefighters can choose to light up the LED light plate 500 or the laser spotlight assembly 600 according to the needs of the scene. The principle of using the laser beam emitted by the laser emitter 620 to explore the environment in the fire field is as follows:
[0038] 1. Obstacle visualization: When the laser beam encounters an obstacle, it will form a breakpoint or deformation, so that the firefighter can judge the dangerous structure in front of him without physical contact, such as walls, collapsed objects, etc., reducing the risk of collision.
[0039] 2. When the laser beam penetrates the smoke, the smoke particles will undergo "Mie scattering" with the laser beam, forming a visible laser light curtain in the air. The laser beam makes the flow trajectory of the smoke particles visualized, allowing the firefighter to distinguish the direction of the airflow in the fire field with his naked eye, and judge the change of air flow speed according to the movement of smoke particles in the light curtain.
[0040] The actual application scenarios of the laser beam emitted by the laser emitter 620 are as follows:
[0041] 1. Determine the location of the fire source and the direction of the fire spread
[0042] Smoke is usually generated from the fire source and spreads with the airflow, and its flow direction can help firefighters quickly locate the approximate position of the fire source. By observing the movement path of the smoke (such as upward, lateral or sinking), the trend of fire spread can be predicted, for example, high-temperature smoke upward may indicate vertical spread, while lateral flow may indicate that the fire is spreading to adjacent areas. The "horizontal line" or "cross" laser emitter can scan the smoke in all directions. Since the laser beam visualizes the smoke particles, the direction of the smoke flow is obvious at a glance, helping firefighters quickly determine the direction of the fire source, find an escape exit, and correctly use the smoke exhaust machine to prevent backdraft.
[0043] 2. Plan a safe route
[0044] The direction of the smoke flow can indicate the dynamics of the airflow in the fire field. Firefighters can approach the fire source against the direction of the smoke flow (as there may be more oxygen near the source of the smoke), or choose a relatively safe rescue path by avoiding areas where smoke is concentrated. If the smoke suddenly changes direction (such as due to changes in ventilation caused by broken doors and windows), it may indicate a sudden change in the fire (such as backdraft or deflagration), and the action strategy needs to be adjusted in time. The "horizontal line" or "cross" laser emitter can scan the terrain in all directions, quickly determine the outline of the fire field by judging the "breakpoint" and "deformation" of the beam, and at the same time, the laser beam can penetrate the smoke to form a light curtain, allowing teammates to perceive each other's positions and prevent teammates from falling behind.
[0045] 3. Evaluate the risk of building structure
[0046] Smoke pouring out of gaps such as door cracks and ceiling cracks may indicate that the structure of the area is damaged or there are high-temperature gases, and attention should be paid to the risk of collapse. Smoke sinking may be due to a decrease in fire temperature or insufficient ventilation, indicating the risk of potential smoldering or oxygen depletion, and attention should be paid to the risk of suffocation. The laser beam emitted by the laser emitter 620 visualizes the flow direction of the smoke, assisting the firefighter in observing the direction of the smoke to avoid danger.
[0047] Please refer to Figure 3 and Figure 4 In an embodiment, a plurality of blind holes 651 are formed on the outward side of the compression ring 650, and the plurality of blind holes 651 are arranged around the lens 640. The blind holes 651 act as fulcrums to facilitate the rotation or disassembly of the compression ring 650.
[0048] In an embodiment, the outer wall of the compression ring 650 is in interference fit with the hole wall of the mounting hole 321, and the compression ring 650 can be pulled out of the mounting hole 321 by applying force, making the assembly and disassembly of the compression ring 650 simple.
[0049] Please refer to Figure 2 In an embodiment, the fire-fighting flashlight 10 further comprises a main control board 710 and a secondary control board 720, the main control board 710 is electrically connected with the secondary control board 720, the main control board 710 is located in the lamp body 100, the power supply 400 is electrically connected with the main control board 710, and the secondary control board 720 is arranged in the handle 310.
